Actor Lee Kwang-soo has once again warmed fans’ hearts after openly speaking about his longtime girlfriend, actress Lee Sun-bin, in newly released behind-the-scenes footage from Netflix’s Jae-seok’s B&B Rules!.

The couple, who have been publicly dating since 2018, are already considered one of the most beloved celebrity pairs in South Korea. Their relationship has often been praised for its stability and longevity, particularly in an entertainment industry where public romances can face intense scrutiny.

In the newly released unaired footage, the conversation began when guest Lee Hyori asked actor Byeon Woo-seok whether he was currently dating anyone.

Byeon Woo Seok immediately replied that he did not have a girlfriend, creating a humorous moment among the cast.

Before the conversation could move on, Lee Kwang-soo jokingly interrupted several times, saying, “I do, noona,” drawing laughter from everyone present.

The playful exchange quickly shifted the focus toward his relationship with Lee Sun-bin.

Seeing the opportunity for more teasing, musician Lee Sang-soon jokingly asked his wife Lee Hyori why she had not directed the same question toward Kwang-soo. Lee Hyori immediately replied that there was no need because everyone already knew about Lee Sun-bin.

She then asked whether the actress enjoyed drinking alcohol.

Lee Kwang-soo answered that she does not drink, leading to another affectionate conversation about his girlfriend.

The discussion became even more heartwarming when Lee Hyori revealed that she was a fan of one of Lee Sun-bin’s dramas. She specifically mentioned how much she enjoyed Work Later, Drink Now, the popular comedy-drama in which Lee Sun-bin starred.

That comment prompted Lee Kwang-soo to share a personal story.

According to him, Lee Hyori had once told Lee Sun-bin at an awards ceremony that she enjoyed watching the series. The compliment apparently left a lasting impression on the actress.

Kwang-soo revealed that after the encounter, Lee Sun-bin talked about Lee Hyori’s praise repeatedly, bringing it up once or twice every week because she was so happy about it.

The anecdote immediately drew smiles from the cast and highlighted what Kwang-soo described as one of Lee Sun-bin’s most charming qualities.

Lee Hyori responded warmly, saying that Lee Sun-bin is kind, adorable, and beautiful, before adding that Kwang-soo was truly fortunate.

Without hesitation, the actor smiled and thanked her.

The compliments did not stop there.

Lee Hyori then turned the praise back toward Kwang-soo, noting that she had heard countless stories about his kindness over the years. According to her, Lee Sun-bin is fortunate as well because she is dating someone known for being warm-hearted and considerate.

Actress and entertainer Ji Ye-eun joined the conversation by highlighting another quality that makes Kwang-soo appealing.

She pointed out that he is genuinely funny, adding that making people laugh consistently is much harder than many people realize.

The comment generated another round of laughter among the cast.

For fans, the exchange offered a rare glimpse into how naturally and comfortably Lee Kwang-soo speaks about his relationship. While many celebrity couples prefer to avoid discussing their personal lives publicly, Kwang-soo has occasionally shared small stories that reveal the affection and admiration he has for Lee Sun-bin.

Their relationship has become increasingly admired over the years because of its longevity. Having publicly confirmed their romance in December 2018, the couple has now spent nearly a decade together, a remarkable achievement in the entertainment world.

Rather than generating headlines through dramatic revelations or relationship rumors, Lee Kwang-soo and Lee Sun-bin continue to win over fans through simple moments like this one—moments that showcase mutual respect, affection, and genuine happiness.

The newly released footage may have been intended as a lighthearted bonus clip, but it ended up reminding viewers why the couple remains one of Korean entertainment’s most beloved long-term relationships. From Kwang-soo’s proud smile when talking about Sun-bin to the compliments exchanged by everyone around them, the conversation painted a picture of a relationship that continues to enjoy widespread support from both colleagues and fans alike.
